It's a user-facing issue: HTTP requests for URLs embedded in the blockchain will be fired regardless if I'm running a local instance. Autoembed can be turned off, but that's not ideal.
Ah i understand, thats why VPN & TOR was invented xD
If people click links, same issue. Memo could filter imgs thru their server so no IP addr is leaked. Would use more server resources though. Someone want to provide free img proxy?
Oh jeez, we have VPNs, TOR, web based proxies, what more u need and who cares :P
